So, I just had another failed attempt at the switch piece. Meaning, things are happening that I don't expect when I'm working the materials. So that means I have a bit of a learning curve to reliably achieve the physical specs and aesthetic results that I have pictured in brain. No biggie; but I'm not gonna let it hold up the run or the "show-me". Looks like I'm going to present with a less than stellar switch tomorrow, with some description of what it is I'm shooting for. That'll give you kids plenty of time to shoot down the circuit concept I have going on while I work on the switch in the off hours and move along with run#9.
Speaking of which, this is a really simple internals scenario; but it's doing everything exactly that I want to see done. One of those things is getting the make/break contact away from the battery. When I made the Dublin'(s), the make/break was silver-on-silver and isolated from the battery. Well, I've been noticing that I rarely, almost never, have to clean the contacts and (as they're exposed) I can never see a visible spark at the make/break either (lights off and all). . . . . and I'm consistently running a 0.16Ω build in there. This got me to very unscientifically suspecting that the coating on our battery contacts is designed for good conductivity; but with no mind to it being a make/break. Furthermore, whatever contact material we use, it's certainly not of the exact same composition and conductive properties as the coating on a battery. With an external, silver/silver contact, I'm hoping to arrive at some of the same benefits as I'm seeing in the Dublin'. Mind you, it's nothing like it structurally. It's a top switch. Also, just by happenstance, I've got that neg. leg running straight to the atomizer. (not to the 510 . . .. to the atomizer).
